Rotary sign board

Abstract

A rotary sign board is installed around the outer periphery of a post in an existing building in such a manner as to be rotated at a predetermined speed, thereby enhancing the advertisement effect. The rotary sign board includes a support portion for surrounding the outer periphery of the lower portion of a cylindrical post; a cover frame for surrounding the outer periphery of the post and having a transparent window formed along the outer peripheral surface thereof; a rotary body disposed in parallel relation with respect to the outer periphery of the post at the inside of the transparent window of the cover frame; a driving portion fixed to abut against the one top side of the cover frame for providing a rotary force to the rotary body; a rotary body support portion provided at the inside of the cover frame; a rotary portion for rotating the rails of the rotary body; and a support rod fixedly mounted to each side of the support portion.

 a cover frame for surrounding the outer periphery of the post in predetermined thickness and width, fixed supportably to the rack of the support portion, and having a transparent window formed along the outer peripheral surface thereof; 
 a rotary body disposed in parallel with respect to the outer periphery of the post and disposed between the cylindrical post and the transparent window of the cover frame, the rotary body provided with a cylindrical display panel displaying advertising information and with a rail fixedly coupled to each of a top and a bottom outer peripheral portions of the display panel through an insertion groove for receiving each of the top and bottom outer peripheral portions of the display panel; 
 a driving portion fixed to abut against a top side of the cover frame and for providing a rotary force to the rotary body; 
 a rotary body support portion provided between the cylindrical post and the cover frame, secured to the cover frame at one end thereof, and rotatably supporting the rotary body; 
 a rotary portion for rotating the rails of the rotary body by the rotary force applied from the driving portion; and 
 a support rod fixedly mounted to each side of the support portion in such a manner as to abut with the ground at the one end thereof. 
 
   
   
     2. The rotary sign board as defined in  claim 1 , wherein the support portion has a plurality of circular support members in such a manner that a side end of each support member is coupled to a side end of an adjacent support member, thereby forming the round band shape, and with the coupling force thereof, the support portion is secured to the outer periphery of the post. 
   
   
     3. The rotary sign board as defined in  claim 1 , wherein the support portion further has a plurality of screw holes formed on a face abutting with the outer periphery of the post and a fixing bolt fastened to each of the plurality of screw holes. 
   
   
     4. The rotary sign board as defined in  claim 1 , wherein the cover frame has a cylindrical metal panel disposed along the inner and outer peripheries thereof to support an internal structure thereof, and the transparent window is formed of a transparent resin film or a cylindrical resin panel disposed along the outer periphery thereof. 
   
   
     5. The rotary sign board as defined in  claim 1 , wherein the display panel is formed of a generally cylindrical resin panel having given rigidity such that the shape is not deformed even during rotation of the rails. 
   
   
     6. The rotary sign board as defined in  claim 1 , wherein the rotary body support portion is disposed in a radial direction with respect to the post and provided with a plurality of support shafts each having one end fixed to an inner periphery of the cover frame and a support roller rotatably coupled to the other end of each of the support shafts for supporting the rails of the rotary body. 
   
   
     7. The rotary sign board as defined in  claim 1 , wherein the driving portion comprises a driving motor fixed at the top or bottom side of the cover frame and a decelerator connected at an input shaft to a rotary shaft of the driving motor and at an output shaft to the rotary portion, for increasing and decreasing the rotary force thereof. 
   
   
     8. The rotary sign board as defined in  claim 1 , wherein the rotary portion is connected to the output shaft of the decelerator for rotating the rotary body with the rotary force applied from the driving portion and comprises a friction wheel for rotating the rail of the rotary body by the friction force thereof and a pressurizing assembly for pressurizing the rotary body against the friction wheel, thus providing a given friction force between the rail and the friction wheel. 
   
   
     9. The rotary sign board as defined in  claim 8 , wherein the pressurizing assembly is disposed in a radial direction with respect to the post between the cylindrical post and the cover frame and provided with a spring guide bar secured to the inner periphery of the cover frame at the one end thereof and forming a spring support end at the other end thereof, a spring guided by the spring guide bar and supported at the one end thereof by the spring support end, a pressurizing roller frame pressurized against the friction wheel by the other end of the spring, and a pressurizing roller rotatably coupled with the pressurizing roller frame around the shaft parallel to the shaft of the friction wheel and contacted with the rail of the rotary body to pressurize the rail. 
   
   
     10. The rotary sign board as defined in  claim 1 , wherein the support rod further comprises a length adjustor screwed with the lower end thereof for adjusting the length thereof. 
   
   
     11. A rotary sign board comprising:
 a support portion provided with a plurality of circular support members each coupled at the side end thereof with the side end of the adjacent support member to form a round band shape, such that with coupling force thereof, the support portion is secured to the outer periphery of a post, and with a rack having a given width along an upper outer periphery thereof for supporting given load applied over the rack; 
 a cover frame for surrounding the outer periphery of the post in predetermined thickness and width, fixed supportably to the rack of the support portion, and having a transparent window formed along an outer peripheral surface thereof; 
 a rotary body disposed in parallel with respect to the outer peripheral surface of the post and disposed between the post and the transparent window of the cover frame, the rotary body provided with a display panel displaying advertising information and formed of a cylindrical resin panel having given rigidity capable of maintaining the shape during the rotation of the rail and with a rail fixedly coupled to each of a top and a bottom of the display panel; 
 a driving portion fixed to abut against a top side of the cover frame and for providing a rotary force to the rotary body; 
 a rotary body support portion provided between the post and the cover frame, secured to the cover frame at the one end thereof, and rotatably supporting the rail of the rotary body; and
